Place all ingredients in a large stock pot, fill with cold water, bring to boil, turn down to simmer; remove scum with a spoon.
Simmer for 2.5 – 3 hours.
Cool slightly, remove the meat, toss the spent veggies and herbs; strain into two 1/2 gallons jars through a fine strainer.
Remove congealed fat off the top when the stock is cooled. Or not.
